# What are some experiments verifying Maxwell's 4th equation?

Please give me the link to some paper, website or book that you know about which discusses in detail some experiments which quantitatively verify Maxwell's 4th equation, which is $$\quad \nabla\times{\bf B} = \frac{1}{ c^2}\frac{\partial{\bf E}}{\partial t} + \mu_0{\bf J}$$

I am specially interested in the case where the electric field is constant and where Maxwell's equation becomes

$$\quad \nabla\times{\bf B} = \mu_0{\bf J}.$$

• Raja, please check how the curvature of the wire and by this the acceleration of the charges induces the magnetic field. Dec 3, 2015 at 17:09
